Why doesn't lava melt the rock around it if it lava usually melts rock?

It takes quite a lot of heat to melt rock, and whatever is melting that rock must loose heat in the process. When molten rock comes out of a volcano, it is closer, in terms of temperature to solidifying than the surrounding rock is to melting. So the lava will cool and harden before the surrounding rock has a chance to melt, especially since the lava is also losing heat to the air. In some cases the surface rock may melt, but in fairly small amounts.

What does the liquid inside of a lava lamp consist of?
It is usually wax that melts as the lamp is turned on. When it is heated, it then begins to float around with the convection current created by the heat-generating lamp, thus creating the "lava" effect.
